C8051F000-GQR

Overview

The C8051F000-GQR is an 8-bit mixed-signal microcontroller from the Silicon Labs C8051F0xx family, housed in a 64-pin TQFP package. It features a high-speed 8051 CPU core capable of up to 25 MIPS at a 25 MHz clock frequency. The device integrates 32 KB of ISP Flash memory and 256 bytes of internal SRAM. Key analog peripherals include a 12-bit SAR ADC with up to 8 external inputs and two 12-bit DACs. Digital interfaces encompass SMBus, SPI, and UART. Operating voltage ranges from 2.7 V to 3.6 V, with a specified operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates a pipelined 8051 CPU core delivering up to 25 MIPS throughput.
• Includes on-chip JTAG debug circuitry for full-speed, non-intrusive in-system debugging without external emulators.
• Features a 12-bit SAR ADC with programmable gain amplifier and data-dependent windowed interrupt generator.
• Provides concurrent hardware support for SMBus, SPI, and UART serial communication ports.

Applications

• Industrial control systems requiring mixed-signal processing
• Sensor interface modules utilizing integrated ADC and comparators
• Embedded applications needing in-system programming via ISP Flash

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package variant. Check current lifecycle status as this series may be designated not recommended for new designs. Ensure environmental compliance documentation aligns with project requirements before finalizing procurement.

Selection Notes

Select this model when a complete mixed-signal solution is needed within a single chip. The integration of 12-bit ADCs and DACs reduces external component count. Consider the 256-byte RAM limit for complex algorithms. Verify that the 64-pin TQFP footprint fits the target PCB layout constraints compared to smaller package options in the same family.

Part Context

This component belongs to the C8051F0xx mixed-signal MCU family by Silicon Labs. It shares architectural similarities with variants like the C8051F005, differing primarily in memory size and peripheral availability. The GQR suffix indicates the tape-and-reel packaging format suitable for automated surface-mount assembly processes.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult official Silicon Labs resources for end-of-life notifications or recommended upgrades within the C8051F series.
